Abstract: Due to the radioactivity of tritium special equipments are necessary for the study of the behaviour of tritium and its decay product He-3 in metals to prevent tritium releases into the environment. This JÜL-report gives a detailed presentation of a 370 TBq high pressure tritium charging apparatus which is built according to the principle of multiple containment. The primary containment is an all metal UHV apparatus constructed using only tritium compatible materials. All components of the high pressure loading apparatus, where certain tritiumpermeation due to high pressures and temperatures may occur, are surrounded by further volumes which are capable of retaining the tritium in case of leckage or break of the first wall. The whole high pressure charging apparatus is placed inside a secondary containment which is constructed like a stainless steel glove box and contains an integrated tritium cleaning system. The 370 TBq tritium are stored in uranium tritide. In the sample chamber pressures up to 26 bar and temperatures up to 1000 °C can be obtained. For the preparation of metal tritide samples pressures in the range of 10$^{-7}$ mbar are necessary which can be achieved by one turbomolecular- and two iongetterpumps, to reduce oxidation effects. In addition, the risks of tritium and further possibilities to charge metals with tritium are discussed. This new 370 TBq facility to charge metals with tritium expands the experimental possibilities in comparison to the existing 37 TBq tritium equipment where only sample temperatures up to 600 °C and tritium pressures up to 2.5 bar are possible.
